TBHQ is the considerably more memorable
and catchy name for tertiary butylhydroquinone. This is a fat preservative that
can be added to dog food in order to improve its shelf life. Unfortunately
though, it may be somewhat unhealthy for your pup and many experts now
recommend avoiding it where possible. What’s worse is that it also finds itself
in a number of human foods where it is no less harmful.
What Is TBHQ?
The chemical preservative TBHQ isn’t
only found in dog food but also finds use in a number of other products.
Specifically, it can be used to stabilize some explosive compounds and is also
used in varnishes, lacquers, skincare products and resins. On top of that, it
can also be found in a number of food products aimed at humans including crisps
and fast foods.
TBHQ is closely
related to butane and is only permitted in amounts of up to 0.02% in
consumables aimed at people by the FDA. This should right away be cause for
concern – especially when you consider that the same restrictions do not apply
to pet food.
Risks
In high doses (1-4 grams), TBHQ can
lead to nausea, delirium, tinnitus, vomiting and weakness. It has also been
suggested to be play a role in hyperactivity in children and potentially asthma
and dermatitis. It is thought to exacerbate ADHD. On top of all this, it may
also alter estrogen levels in women.
In laboratory
settings, TBHQ has been shown to be precancerous for animals and can lead to DNA damage. Then again, there is still need for further studies
in this regard and some research has even suggested that the substance could
help to prevent cancer.
Recommendations
There is no cause for alarm when it
comes to human food. The restrictions put in place by the FDA are based on
research and studies and should ensure that there are no harmful side effects
from products with this small inclusion.
Likewise, while there
may be some risks associated with pet food containing TBHQ, it’s also true that
many pets eating these products go on to live full and healthy lives. With no concrete
evidence yet proving a link between TBHQ and cancer, there’s no need to
take decisive action.
That said however, if
you are concerned about your dog’s health and want to go the extra mile then it
certainly can’t hurt to avoid TBHQ until more evidence is available. There are
an increasing number of natural dog foods on the markets these days that are
completely free from artificial flavorings and preservatives.
As always, stay safe
